Examples with IBinder android.os.IBinder used on opensource projects

Example 61 with IBinder

use of android.os.IBinder in project platform_frameworks_base by android.

the class KeyStoreTest method testBadToken.

public void testBadToken() throws Exception {
    IBinder token = new Binder();
    OperationResult result = mKeyStore.update(token, null, new byte[] { 0x01 });

}

use of android.os.IBinder in project platform_frameworks_base by android.
